-BUTT-ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 620,858, dated March 7, 1899.

Application led April 30, 1898. Serial No. 679,381. (No model.)

To all whom it may concern:

Be it known that I, DAVID SINCOCK, a resident of Clyde Park, in the county of Park and State of Montana, have invented certain new and useful Improvements in Butt-Adjusters; and' I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains .to make and use the same.

My invention relates to an'improvement in butt-adjusters for grain=binders, the object and B is the deck of a binder, to which said adjusteris connected by any approved means. The adjuster is composed of a frame C, comprising atop and bottom section o and b, approximately parallel and made with rounded ends 1 2, connected between their ends by a brace-bar 3. The top and bottom sections are preferably larger at one end, 1, than at the other end, 2, and preferably slightly curved on their outer face. A shaft 6 is mounted in the larger ends 1 of said sections and provided with pulleys 7 7 at each end, said pulleys being concentric with the rounded ends 1 of said frame. Said shaft is preferably provided at one end with an extended bearing, on which is secured a gear-wheell 8, adapted to be rotated by any suitable gearing. The smaller end 2 of said frame is provided with a shaft 9, journaled between said top and bottom sections and provided with pulleys 10 10, secured thereto and concentric with the curved ends 2 of said frame.

A plate or platform 1l, preferably of sheet metal, is located on the curved upper edges of the sections c ZJ and provided with ianges 12, adapted to be secured to the top and bottom faces of the frame C, said plate or platform adapted to receive thebutts of the straw. The plate 11 is provided at each end with a tongue 13, approximately the width of the space between the pulleys and of sufficient length to project over the respective shafts 6 and 9, whereby to prevent any straw from entangling itself in said adjuster. An endless straw-carrier D is mounted on said frame and adapted to run on pulleys 7 7 and 10 10 and continuously move around said frame. The carrier consists of two parallel straps or belts 14 14, provided at oneend with buckles 15 15 and at their other ends with a series of holes or perforations 16 16 to receive the tongues of said buckles, whereby to permit.

of the tightening and loosening of said carrier or its removal from the frame. A series of connecting bars or slats 17, approximately the length of the height of said frame, is secured in cut-out portions near their ends to the straps 14 14 a sufficient distance apart and of sufficient thickness to most eectnally carry the straw along and smooth the butts of the same against the plate or platform 11,

whereby to even the butts of straw. Plates or guides 18 18 of the same'general outline as top and bottom sections a and b, but larger, are secured to the outside of said sections and project at their edges beyond the same, whereby to form a guide for the connectingbars 17 and also to keep the straw compact and smooth and not allow the same to pile up and stop the working of the adjuster.

v All the pulleys are made hollow,with their upper sides closed to prevent straw being entangled therein. platform slightly curved between its ends the slats will be maintained in close contact therewith. Y

My improved adjuster is much more durable than canvas-apron adjusters, is more effectual in the performance of its functions, is very cheap to manufacture, and is simple in construction.

It is evident that numerous slight changes might be made in the general form andv arrangement of the several parts herein shown and described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details herein By making the plate. or

set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A butt-adjuster consisting of a frame comprising parallel sections and a cross-bar oonnecting the same, shafts mounted at the respective ends of the frame, pulleys on said shaft, a sheet-metal platform secured to the parallel edges of the parallel sections of the frame, integral flanges projecting from the edges of said platform and secured to the sec I 5 tions of the frame, integral tongues projecting inwardly from the respective ends of said sheet-metal platform and terminating in proximity to said shafts, and an endless carrier passing over said pulleys and platform, sub stantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

. DAVID SIN COCK.
